Photos, videos and names in reply tweets will no longer count
Social media site Twitter has confirmed users will be able to compose longer tweets within the existing 140-character limit.
It says photos, videos and @names in reply tweets will no longer count toward the limit.
It says the this will make conversations "faster and more intuitive for people who come to Twitter everyday and those who are new to the service".
While people will now be able to retweet and quote tweet themselves, and any new tweet beginning with an @name will be seen by all followers.
Twitter CEO and co-founder Jack Dorsey says: "One of the biggest priorities for this year is to refine our product and make it simpler".
"We're focused on making Twitter a whole lot easier and faster".
"We're not giving up on the idea of Twitter being in the moment. That concept of brevity, speed and live conversation - being able to think of something and put it out to the world instantly - that's what's most important," he added.
It says the updates will be available in "the coming months".
Here is what will change:
Launched solely as text, tweets have evolved in the past 10 years to include photos, videos, GIFs, polls and Quote Tweets - all of which have subtracted from the overall 140-character count.
In addition to these changes, Twitter says it will continue to explore ways to make the service simpler and more intuitive.
